We already know that a critical error occurs on devices with 64-bit processor Apple A7, A8, A8X, A9 and A9X: iPhone 5 and newer, iPad Air and iPad Mini 2 and newer, as well as the 6 th generation iPod Touch. The OS version does not matter. On older generations failed to reproduce the error devices.
The bug does not work under any other circumstances, so strongly urge you to refrain from experiments at least as long as Apple does not announce officially about finding a way to restore the device to working condition. It is unknown whether the company will replace the affected device or will it be a software recovery method.
